Answer:
The approximate cost during the year 1987 was $7,533
Step-by-step explanation:
The complete question in the attached figure
we have
y -----> is the cost in dollars
x -----> is the year
Looking at the graph we have the points
(1983,5,047) and (1991, 10,019)
To determine the cost in the year 1987, find out the midpoint between the two given points
The formula to calculate the midpoint between two points is equal to

substitute the values


therefore
The approximate cost during the year 1987 was $7,533
23-8= 15 degrees it increased by 15 degrees
N*(21/100)=(700/100)
n=(700/100)/(21/100)
n=(700/100)*(100/21)
n=700/21
n=33+1/3
So <em><u>thirty three</u></em> $0.21 pencils can be purchased for $7.00.
Answer:
The equation to determine the number of days Margo has owned the plant is
.
Step-by-step explanation:
Given:
Actual length of the tree = 5 cm
Current length of the tree = 65 cm
Per day growth Rate of plant = 2.5 cm
Let number of days she owned the plant be 'x'
Now We can say that,
Current length of the tree is equal to sum of Actual length of the tree and Per day growth Rate of plant multiplied by number of days she owned the plant.
Farming the above sentence in equation form we get;

Hence the equation to determine the number of days Margo has owned the plant is
.
